Since i can stop the fan clutch with my hand when the car is hot - i think it's about time for me to change it. But is it fan clutch gone bad or there might be something wrong with belts or with something else??? And what is the price for fan clutch for 535 '91 and where is the best place to buy (taking delivery time in consideration..)?? I hope this will cure my problem.. with running hot in traffic... One more question where exactly is the bleed screw on radiator....I did some bleeding with one screw above the thermostat and i cant find the second one... Thank you!!!
